Four of Facebook’s video partners made the director’s cut due to their early success with applications upgraded for timeline: Viddy, Vevo, Izlesene, and Dailymotion.

Viddy has doubled its average daily sign-ups since upgrading to timeline, and monthly average users have soared to more than 920,000 from 60,000. The mobile app has seen more than 9 million interactions with its content via the social network.

Vevo relaunched its site and its apps for the iPhone and Android to add deep integration with the social network and its open graph, and it reported that published actions on Facebook skyrocketed 600 percent in March compared with February, with referrals from the social network jumping 130 percent. Vevo said 60 percent of its Facebook referral traffic now comes from open graph stories, adding that moving to Facebook-only registration has boosted its daily total by 200 percent.

Izlesene grew its user base 16-fold after its open graph update, and the Turkish site has seen its monthly average users skyrocket from 250,000 to more than 4 million, with the number of videos viewed daily by users more than tripling.

Dailymotion has been added to more than 9 million Facebook users’ timelines since its open graph update, with more than 6 million people visiting the site daily via Facebook, and more than 2 million daily stories published back to the social network.

Facebook also offered best practices for video apps in a post on its developers blog:

Be transparent:On websites integrated with open graph, it should be clear to users what will take place on the site and back on Facebook, and it should be easy to find the log-in option. For example, Vevo shows the benefit of personalization immediately at the registration process, and provides users with a clear social on/off control. Similarly, Viddy’s website immediately points out to the user where he or she can sign into the app and add it to their timeline.

Provide social context throughout: The social context should continue throughout the user’s experience. For example, Vevo shows a face pile on the left side of the website that the user sees from the start, and it surfaces social features with each video. For mobile apps, the social experience should extend through mobile platforms so people can engage with their friends wherever they are.

A/B test: Understand and constantly test how to optimize the user experience. Izlesene optimized its experience by performing A/B tests for the auth dialog. In the process, it learned that users will accept the dialog if they are given more context. Izlesene added a face pile of friends who use the app, which has since resulted in increased conversion.
